sh 杀死远程Gulp进程在转发端口上运行LiveReload

Posted 2021-05-07

# I often run gulp-livereload on a remote server using port forwarding with plink or putty.
# Putty and plink crash somewhat frequently when carrying on this process remotely. 
# This function - executed in a different terminal on remote host cleans up any zombie gulp process and the parent shell -
# as these zombie processes prevent port forwarding from working when trying to restart gulp.

function killGulp {

  # necessary otherwise when piping ps output through grep,
  # output includes grep command to find gulp
  
	p=`mktemp`
	ps alx > $p
	findgulp=($(grep "gulp\s" $p))
	
	# gulp process id
	pid=${findgulp[2]}
	
	# parent bash process id
	ppid=${findgulp[3]}

  kill -s SIGKILL $pid &>/dev/nul
  kill -s SIGKILL $ppid &>/dev/nul

}
